Treaty of Medina del Campo 89: Ferdinand and HVII offered mutual protection, agreed not to harbour rebels or pretenders, and arranged a marriage alliance between Arthur and Catherine
Arrangements for the marriage did not go smoothly, Ferdinand proved reluctant to allow the marriage to go ahead as long as HVII remained threatened by Warbeck, arguments over Catherine's dowry size
The details of the marriage were finally finalised in 99 and took place in 01, however Arthur's death in 02 brought complications of HVII's relationship with Ferdinand
HVII immediately suggested CoA marry Henry, but Fe was reluctant, said the marriage needs papal dispensation which would be costly
04 Isabella of Castille died, making Fe lose quite a lot of political power, Sp fell into a succession uncertainty between Juana and Fe, HVII backing Juana which ended up being a poor move to make
In Jan 06 Philip of Burgundy and Juana I of Castile were forced to take refuge in Eng and HVII manipulated them into signing Treaty of Windsor
Philip of Burgundy died, Fe takes the throne, and ensures that Henry's and Catherine's marriage doesn't take place in his lifetime
